7 Claims. (Cl. 220-71) This invention relates to rolling rings forbarrels, such as metal barrels or drums in which liquids are stored orshipped, and more especially it relates to rolling rings of thecharacter mentioned that are composed principally of rubber.

The use of rubber rolling rings for metal barrels has provedadvantageous for the reason that such rings do not mar or damagepolished wooden floors over which the barrels are rolled, and do not maror' damage the sides of other barrels or drums that may come violentlyinto contact therewith. The problems involved in the use of rubberrolling rings for barrels include the provision of means for mountingand retaining the rings on the barrels, the provision of closely abuttedends in cases where the rolling rings are split, and the provision ofmeans for maintain- 4 may not enter therebetween.

The chief objects of the invention are to provide an improved rubberrolling ring for barrels; to provide in an improved manner for attachingrubber rolling rings to barrels; to provide improved metal elements foroperative association with rubber rolling rings to secure the latter tobarrels; to provide for yconcealment of the aforementioned metalelements; to obtain closely abutted ends of the rubber structureconstituting a rolling ring; to provide in an improved manner formechanically interlocking the metallic elements and the rubber elementsof rubber rolling rings; and to provide for maintaining the lateralmargins of a rubber rolling ring in close contact with the surface of abarrel. Other objects will be manifest as the description proceeds.

Of the accompanying drawings:

Fig. 1 is a side elevation of a metal barrel, and a .pair of theimproved rolling rings operatively mounted thereon, a part of the barreland rings being broken away and in section;

Fig. 2 is a section on the line 2-2 of Fig. 4;

Fig. 3 is a section on the line 3-3 of Fig. 4;

Fig. 4 is a fragmentary central longitudinal section, on a larger scale,of the improved/rolling ring shown in Fig. l and the barrel wall onwhich it is mounted, said section being taken at the abutted ends of therubber component of the ring, and showing means for drawing together theends of the metal element of the ring;

Fig. 5 is a section similar to Fig. 4 showing the use of means forholding apart the ends of the rubber structure while the ends of themetal element are drawn toward each other;

Fig. 6 is a fragmentary plan of another embodiment of the invention, apart being broken away to reveal modified means for drawing together theends of the metal element of the ring;-

Fig. 7 is a central longitudinal section of the structure shown in Fig.6, before the ends thereof are drawn together, taken on line 'I-'I ofFig. 6; and

Fig. 8 is a section on the line 8-8 of Fig. 7.

Referring to Fig. 1 of the drawings, there is shown a sheet metal barrelor drum I Il of any preferred or conventional type, the wall of saiddrum being formed with two circumferentially disposed ribs orcorrugations II, II, which ribs extend outwardly from the wall or shell,and are of transversely dished or concave contour in their medialcircumferential region, as is best shown at I2. Figs. Zaand 3. 'I'heribs I I do not extend completely 1.about the drum, but are discontinuedin a narrow region thereof that is in alignment with the bung hole I3 ofthe drum, longitudinally of the latter as shown in Fig. 1, to enable thedrum to be completely emptied. The ribs II serve as seats for respectiverolling hoops I4, I4 that embody the invention.

Each rolling hoop I4 comprises a resilient element I6 of rubber orrubber-like composition, and a contractile metal element I'I upon whichsaid rubber element is mounted, both of said elements being formed assplit rings and the rubber element being positioned upon the outercircumference of the metal element. The metal element Il is alongitudinally arcuate structure. which, in its medial longitudinalregion is transversely shaped complemental to the contour of a` drum ribI I so as snugly to t thereover. Each lateral marginal portion of theelement Il extends radially outwardly, parallel to the plane of theelement, for a substantial distance, and there is reversely andobliquely bent so that when the rolling ring is on the drum the lateraledges ol thevelement I1 are in spaced relation to the wall of the drumand to the adjacent radially extending portions of the element. Thearrangement is such that the marginal portions of the lelement Ilconstitute hooks I8, I8, which hooks are utilized for the retention ofthe resilient element I6 as presently will be explained. For retainingthe metal element il upon a drum I0, the respective end portions of theelement are incised, at points spaced from the ends thereof, anddeformed outwardly to provide respective apertures I9 each having araised tongue 20 on the side thereof nearest the adjacent end of theelement, and an upstanding ear 2 Iy on the opposite side of saidaperture. Received in each aperture I9 is a hook-like member 22 that isformed with a notch or slot in which the tongue 20 at the side of saidaperture is receivable. Each member 22 is integrally formed with athreaded stem 23, the two stems being directed toward each other andformed respectively with a right hand thread and a left hand thread.Engaging the threaded stems 23 and spanning the space between theconfronting ends of the metal member l'l is a turnbuckle 24, the samebeing provided with the usual medial hexagonal portion for engagementwith a suitable wrench (not shown). By means of said turnbuckle themetal element l'l may be drawn tightly about the drum I0, upon a rib lthereof, the confronting ends of said element standing slightly apart,as shown. in Fig. 4, when the turnbuckle is fully tightened.

The resilient element I6 may be composed of vulcanized rubbercomposition, or any other resilient composition having similar orcomparable characteristics. The element E originally is made inlongitudinally straight form, but is arranged to be mounted upon themetal element il, and to assume the longitudinally arcuate form of thelatter, prior to being mounted upon a drum lll. In transverse shape theelement i6 has a substantially half-round portion that is outwardlypresented when the element is mounted for use. and which constitutes thetread or wear-surface of the element. The opposite face of 'the element.that is, the face that is inwardly presented during use, is shapedcomplemental to the outer sur face of the metal element l'l, and haslateral portions adapted to be deformed and snapped under the marginalhooks i8 of said element l1, the inner circumferential faces of thelateral portons of element i6 being shaped to rest flush upon thesurface of the drum lll as shown. The length of the resilient element i6is somewhat greater than the length of the metal member i7 so as toextend slightly beyond the respective ends of the latter, and therespective end portions of element I8 are recessed on the under sidesthereof, as shown at 25, 2E, to provide space for the reception of thethreaded hooks 22 and the turnbuckle 2t.

In the mounting of the improved rolling ring upon a drum, the resilientelement 6 is mounted upon the metal element l1 before the ring isapplied to the drum, the split nature of the ring enabling it to bedistended sufficiently to slip over a drum-rib l i. The turnbuckle 24then is started onto the threaded stems 23. This operation isfacilitated by the fact that the hook-like members 22 are somewhatloosely received in the apertures i9 of the metal element l1, so thatthreaded stems 23 may be brought into axial alignment without difficultynotwithstanding the fact that the ends of the ring are spaced apart fromeach other. Because the resilient element l is longer than the metalelement l1, it is necessary to hold the ends of said resilient elementapart from each other until the turnbuckle is fully set up. and to thisend a slotted device 28, Fig. 5 is positioned temporarily between theends of said resilient ele-4 ment. The slot in said device 28 enablesthe turnbuckle to be set up by means of a tool inserted through saidslot. When the turnbuckle is fully set up, the device 28 is withdrawn,whereupon the confronting ends of the resilient element move together,preferably tightly enough to place the adjacent regions of the structureunder slight compressive stress so that a closed juncture is .assured atall times.

The invention provides a rolling ring that is of simple construction,that is easily applied to a dij barrel or drum, that has its marginalsurfaces held tightly against the drum, which has a metal structure soenclosed as to be protected from impact and from contact with corrosivefluids. and which achieves the other advantages set forth in theforegoing statement of objects.

The modified embodiment of the invention shown in Figs. 6 to 8 inclusiveis essentially similar to the embodiment previously described, anddiffers therefrom solely in the means employed for drawing; together thecorirffnting ends of the metal element of the ring. Thus the resilientelement la may be identical with the resilient rlement i6 previouslydescribed except for the size and shape of the recesses 25a. 25u at therespective ends thereof'. '1in metal element lla. may be identical withmetal element il' except that the apertures I9@ in the respective endportions there of are somewhat nearer the end margins of the element.Loosely received in said apertures |9a are respective anchor blocks 30,each block formed with a flange 3l at its lower margin for engagementwith the lip 20a at the side of the aperture lSa. Each a; cher block 3Uis formed with a threaded bore in which is received an end of a screwelement 32, one end of the latter being formed with right hand threadsand the other end being formed with left hand threads. The said screwelement 32 is centrally formed with an integral hexagonal formation 33by means of which it is rotated by any suitable tool, such as a wrench.

The modified embodiment of the invention is mounted upon a hariaE ordrum in exactly the same manner as the embodiment first described. andit pc es substantially all the advantages of the la er.

Other modification may ce resorted to without departing from the spuitof the invention, or the scope thereof' as defined by the appendedclaims.
